We are a startup company in the US and UK.
We have an RCP in beta stage. It's a product targeted at Financial Trading
Systems.
We need an expert to take it to production quality V1.0
We have little funds left, hence we offer a share ownership of the project.
We already have clients in London and Wall Street (or whatever will be
left of it). Clients are investment banks we already work with.

(Note to those less experienced who are thinking to apply:
You won't have enough experience, hence the product will fail, hence it
won't sell, hence you will lose your time and make no profits. Please
spare yours and our time).
